So, it appears that whoever was behind this was at least competent. There's nothing I can do besides think and come to conclusions. Time to get started.
First, why should I care? Besides the most recent developments, even if I somehow managed to not get caught up in a situation like this, I would've done some amount of investigation.
Shawn made an interesting argument earlier, but that's not the main reason. The real point of interest is these strange abilities Ehn discussed earlier, and the key incident was back at the fish store with Mr. Kerloe, Sophie, and the Sentasaurus. Back then, I was too caught up in the situation to focus on the implications, but thinking back, I saw him go outside and use this ability twice - once as a test, and another time to get to the hospital. That's impossible to stage without going far beyond my comprehension, and regardless of the answer, it's far outside the realm of normal possibilities.
So, no matter how I proceed, there's a permanent risk in my life going forward, and I have no choice but to accept it. Flight is relatively basic, but I wouldn't be surprised if there were more unusual - and more dangerous - abilities out there. Hopefully no one can read my thoughts, for example. ...Anyway, I doubt Ehn only contacted us specifically. Between her lack of knowledge on our supposed assigned abilities and her established rules, it's clear this goes beyond just the three of us at the fish store.
Speaking of which, Ehn herself is unusual, but ultimately, her identity is irrelevant. I see her as a dog, but the Sentasaurus thought she was a cat, and Mr. Kerloe probably saw her as a fish or whatever else. Either way, she's not threatening on her own, just annoying, and I doubt she'll come back anyway. I might as well try, just in case. I'm sure she can hear anything she wants to, so she might respond even here.
Sam whispers "Ehn? Are you there?" in an extremely neutral tone.
